본 연구는 국내에서 실내 관상용으로 많이 활용되는 스킨답 서스의 실내재배 시 적정 인공광원, 수경재배 전기전도도 농 도 및 용토를 선발하기 위하여 수행하였다. 실내재배 시 인공 광원은 형광등, 적청 LED, 백색 LED로 처리하였다. 수경재배 시 양액 농도는 EC 1.2, 1.6, 2.0ds·m-1 수준으로 하였고, 재 배용토는 제올라이트, 코코피트, 펄라이트, 황토볼 4가지로 달리하였다. 스킨답서스의 실내 재배 시 줄기 길이는 형광등 과 적청 LED 처리보다 백색 LED 처리에서 길어졌다. 잎의 크기는 적청 LED 처리에서 형광등과 백색 LED 처리보다 커 지는 경향이었다. 엽록소 지수값은 백색 LED>적청 LED>형광 등 순으로 높았다. 수경재배 시 스킨답서스의 줄기길이는 EC 농도가 높아질수록 길어지는 경향이었고, 용토별로 비교하면 제올라이트와 코코피트에서 높은 경향이었다. 엽록소 지수값 도 EC 농도와 비례하여 높아졌고, 용토별로는 제올라이트와 코코피트에서 높았다. 스킨답서스의 생체중도 EC 농도가 높 을수록 높았고, 제올라이트와 코코피트에 높은 경향이었다. 상기 결과들을 종합할 때, 스킨답서스의 NFT를 이용한 실내 재배 시 적정 인공광원으로는 백색 LED를, 수경재배 양액의 농도는 EC 1.6∼2.0ds·m-1를, 그리고 NFT 용토는 제올라이 트나 코코피트가 적합하다는 것을 알 수 있었다.

현대사회는 인터넷과 스마트 기기의 발달로 모든 세대에게 게임을 포함한 디지털 미디어 이용이 보 편화 되었다. 인터넷은 시간과 공간을 초월하고 세대를 넘어서 인간과 정보를 연결한다. 스마트폰의 보급으로 누구나 인터넷에 쉽게 접근하게 되어 미디어 이용이 더욱 증가하고 있다. 스마트폰은 접 근성이 좋고 시간과 장소에 구애 없이 사용할 수 있어서 게임을 포함한 미디어중독에 노출될 수 있 다. 수많은 스마트폰 어플리케이션은 인터넷 세계로 이끄는 요인이 된다. 아버지의 일-가정 양립은 양육스트레스를 증가시키고, 양육스트레스는 게임을 포함한 인터넷과 스마트폰 중독을 예측하는 중 요한 요인이다. 부모의 미디어중독이 자녀의 인터넷 게임중독에 영향을 미치는 측면이 있으므로 아 버지의 미디어중독에 대하여 살펴볼 필요가 있다. 본 연구는 아버지의 양육스트레스와 미디어중독 의 관계에서 부부갈등의 매개효과를 살펴보는 데 목적이 있다. 이를 위해 한국육아정책연구소에서 제공하는 한국아동패널 13차 조사자료를 사용하였다. 자료는 SPSS 27.0 프로그램과 Process macro 4.1 을 사용하여 분석하였다.

Studies regarding the relationship between purchases and happiness have consistently found an experiential advantage: people are happier when purchasing experiential products (e.g., vacations and concerts) than material products (e.g., clothes and electronics) (Caprariello & Reis, 2013; Carter & Gilovich, 2010, 2012; Pchelin & Howell, 2014; van Boven and Gilovich, 2003). This phenomenon (i.e., experiential advantage) may make marketing efforts of service firms or any companies selling experiences relatively more effective and productive in that consumers will derive a great amount of purchase happiness. On the other hand, the same phenomenon may indicate innate challenges and hurdles for firms selling products carrying materialistic features. Considering the material-experiential spectrum, approximately 50% of the industries are seeming faced with this issue. In this research, we propose a solution with which mainly material-focused products can loom more experiential, thereby benefiting from the experiential advantage. In other words, we investigate how material goods can be perceived as experiential and they can offer greater purchase satisfaction compared to when they remain as merely materialistic. Specifically, noting that reasons for experiential advantages are originated from social aspects of experiential goods (e.g., self-presentation to other people, conversational values, reputation-building, etc.), the current study shows that posting on social media can imbue social aspects, which is a key drive of the experiential advantage.

This study analyzed the presence and effect of sexual appeal of plus-size models using Victoria's Secret's Instagram content. A content analysis using roBERTa deep-learning model found that, plus-size models’ sexual appeals increased number of likes and comments, but explicit sexual appeals resulted in less positive sentiments than thin models’.

Influencers have become a critical component of marketing strategy to increase awareness, encourage consideration, and drive purchases. A new type of influencer, computer-generated and artificial intelligence-powered avatars, has emerged amid this boom. Despite the mixed marketing results virtual influencers deliver, they are generally thought to create similar engagement as human influencers. Consumers appear capable of developing complex psychological processes when engaging with virtual influencers. Even though the positive impact of influencers is evident, there is a growing concern about how they can affect consumers' well-being. The feeling of envy is a significant well-being concern in the social media world. Assuming virtual influencers can deliver similar emotional effects as human influencers, can we feel envy towards virtual influencers?

본 연구는 극지 식물플랑크톤의 자외선 영향을 파악하기 위해, Phaeocystis antarctica와 Phaeocystis pouchetii를 대상으로 유색 용존 유기물의 생산과 광반응성을 평가하였다. 강한 자외선에 노출 배양 시, 가시광선 파장대에서 유색 용존 유기물의 흡광도는 두 식물플랑크 톤 모두 배양 초기에 비해 48시간 동안 감소하였다. 반면, 자외선 파장에서는 P. antarctica는 48시간 배양 후, 유색 용존 유기물의 흡광도는 초기 농도에 비해 약 30% 감소하였지만, P. pouchetii의 흡광도는 오히려 10% 증가한 경향을 보였다. 이 결과들은 강한 자외선에 노출될 경 우, P. antarctica이 생산한 유색 용존 유기물은 광분해에 의한 감소로 인해 해수 중 수중 생태계에 자외선 차단 효과는 감소하는 반면, P. pouchetii가 생산한 유색 용존 유기물에 의한 광보호 효과가 더 효율적임을 알 수 있었다. 또한, 자외선 영향 하에서 배양된 P. pouchetii의 배 양액에서 시간에 따라 증가한 유색 용존 유기물의 형광 특성이 지구 거대물질로 알려진 humic-like (C-peak)와 일치하여, 이는 자외선 차단 물질로 알려진 MAAs 생물 생산에 의한 것임을 확인하였다. 이는 기후변화에 의한 성층화가 강화되는 극지 해양환경에서, 광반응성이 낮은 P. pouchetti가 용존 유기물의 증가에 기여할 수 있을 것으로 기대된다.

This study analyzed the effects of fashion creators’ innovativeness and attractiveness on consumer response and orientation toward a sustainable relationship in personal media. A survey was conducted with consumers aged in their 20s and 30s who had experience in sharing video content or writing comments and participating in fashion creators’ real-time broadcasting of personal media. The results show that the innovativeness of fashion creators was classified into originality, opinion leadership, variety, and adventurous spirit, while attractiveness was classified into physical, social, and professional attractiveness. Consumer responses were classified into either emotional or cognitive responses, and sustainable relationship orientation was classified into communication, sharing, and relationship sustainability. The originality and variety of the fashion creators positively affected the emotional and cognitive responses of consumers. Adventurous spirit positively affected emotional response, whereas opinion leadership positively affected cognitive response. In addition, the social and professional attractiveness of fashion creators positively affected consumers’ emotional and cognitive responses. Emotional and cognitive responses positively affected consumers’ sustainable relationship orientation. The originality and opinion leadership of the fashion creators positively affected the three factors of sustainable relationship orientation, while variety positively affected communication and relationship sustainability. Fashion creators' social and professional attractiveness positively affected the three factors of sustainable relationship orientation, and physical attractiveness positively affected relationship sustainability. The results of this study are expected to provide useful data on the direction of fashion startups using personal media and marketing as well as distribution strategies in the fashion industry.

This study investigated whether there is a correlation between the occurrence of hazardous substances such as vibrio, norovirus, radioactivity, shellfish posion, hepatitis A, etc. and media reports, and whether the occurrence of hazardous substances and media reports affect the production, distribution and consumption of aquatic products. The main research results are as follows. First, it can be seen that there is a difference in the relationship between the occurrence of hazardous substances and media reports according to hazardous substances. Second, it suggests seen that the occurrence of hazardous substances and media reports can have a negative effect on the production and the prices of aquatic products. Third, it was found that the occurrence and reporting of hazardous substances had different effects on the distribution margin of aquatic products due to the complexity and rigidity of the distribution structure. Fourth, consumers feel a threat to aquatic products safety and significantly reduce consumption when hazardous substances occur. There is a possibility that concerns about one item may lead to a decrease in consumption of domestic and imported aquatic products that are not related at all to the occurrence of hazardous substances. In conclusion, aquatic products are exposed to various hazardous substances such as vibrio, norovirus, radioactivity, shellfish posion, and hepatitis A. It was found that the occurrence of hazardous substances and its media reports could cause damage to the fishery sector.

This study examined undergraduate students’ perceptions of effects of online course types such as face-to-face classes, online classes, and blended classes using survey data from 331 students during three semesters from 2020 to 2021. There were differences in effects using ‘PPT video’, ‘voice only in PPT’, and ‘real-time zoom’ between theoretical courses and practice courses. In terms of media types for online classes, ‘PPT video’ was perceived as the most effective type by students, followed by ‘voice only in PPT’, ‘real-time video’, and ‘blended media use’ meaning a 2-hour-course mixed with 1-hour PPT video and 1-hour-real-time video. The effectiveness of ‘real-time video’ and ‘blended media use’ was gradually decreased as time went by. Students had difficulties in academic achievement and daily life with online learning. They were eager to return to face-to-face classes after COVID-19 passes. Some online learning media types were preferable to use for face-to-face classes after COVID-19.

Corporate Social Responsibility (CSR) can be defined as corporate activities that contribute to sustainable development and social well-being (Dahlsrud, 2008). Donation-linked activities in which a portion of the revenue is donated to the local community when consumers purchase products can be part of CSR activities (Folse, Niedrich, & Grau, 2010). Consumers now also want to consume "good" CSR activities, purchase "good" corporate products, and “reward” the companies engaged in CSR activities (Bhattacharya & Sen, 2004). Consequently, it is important that companies promote products that are associated with CSR so that consumers can identify the company is doing good (Lii & Lee, 2012). This is because CSR-related products can lead to consumers’ positive responses or evaluation (e.g. Brown & Dacin, 1997), high buying intentions (e.g. Mohr & Webb, 2005), and positive impact on brand attitude or brand equity (e.g. Hur, Kim, & Woo, 2014).

Employing national consumer panels in the US and Korea (N = 767), this research examined how consumer evaluations of graphic sexual ads on social media differ from those of non-sexual ads, and to what extent such evaluations are influenced by different cultural backgrounds (Individualism vs. Confucianism) and sexual self-schema (SSS) levels.

아자리아 챔버레인 실종 사건은 미디어 재판의 대표적인 사례이다. 미디어 담론의 중점을 사건 연루자들에 둔 기사들은 부정적 암시를 내포하는 은유와 문장구조를 통해 편견을 조장하였다. 미디어가 선동한 여론에 의해 챔버레인 가족은 용의자로 몰렸고 그들의 종교 또한 광신적 집단이라는 부당한 비난을 받았다. 결국 아자리아의 부모는 유죄를 선고 받았으나, 증거가 불충분했고 재판 과정과 선고방식이 정당하지 않았다는 근거로 대항 공론 운동이 전개되었다. 챔 버레인 부부의 무죄 판결 이후에도 미디어 재판에 맞서는 시도는 계속되고 있다. 이 사건의 전모는 대중이 넘쳐나는 선정적 뉴스로부터 진실을 구별할 수 있게 하는 교육의 중요성을 시사한다. 종교적, 사회적 편견의 피해자들을 지지하 기 위하여 시민의식을 고양시키고 대항 공론의 장을 정착시키는 일 또한 필요 할 것이다.
